Hi ,
What is sodium Benzoit ? Can I make the ketchup without using it as I would love to make it without preservatives. And instead of sugar can dried grapes (kismis) be added for sweetness for I would love to use less sugar than the one available in markets ?

Tarla Dalal &nbsp&nbsp Hi Akila, yes you can make it without sodium benzoate.. the only thing is you will have to use it within a weeks time.. and regarding grapes.. i am not sure for the sweetness.. But you can adjust the sweetness according to your taste..
